1.定义消息

#define  WM_RMENU_CMD_TEST_1  WM_USER + 202
#define  WM_RMENU_CMD_TEST_2  WM_USER + 203
#define  WM_RMENU_CMD_TEST_3  WM_USER + 204

2.定义消息函数
//
ON_WM_RBUTTONDOWN()
//
afx_msg void OnRButtonDown(UINT nFlags, CPoint point);

3.消息函数实现
void CProductModeling::OnRButtonDown(UINT nFlags, CPoint point)
{
        CMenu menu;
        menu.CreatePopupMenu();
        menu.AppendMenu(MF_STRING, WM_RMENU_CMD_TEST_1, "Test 1");
        menu.AppendMenu(MF_STRING, WM_RMENU_CMD_TEST_1, "Test 2");
        menu.AppendMenu(MF_STRING, WM_RMENU_CMD_TEST_1, "Test 3");

        POINT tpoint;
        tpoint.x = point.x;
        tpoint.y = point.y;
        ClientToScreen(&tpoint);
        menu.TrackPopupMenu(TPM_LEFTALIGN, tpoint.x, tpoint.y, this);

        CDialog::OnRButtonDown(nFlags, point);
}

4.重载命令消息函数
virtual BOOL OnCommand(WPARAM wParam, LPARAM lParam);
BOOL CProductModeling::OnCommand(WPARAM wParam, LPARAM lParam)
{
        switch (LO
